FIELD: machine building.SUBSTANCE: vibration absorber consists of a casing and a resilient element interacting with a unit. The casing is made as a base plate where two guiding sleeves with bottoms turned to the base plate are fixed by a layer of cast polyurethane. Cylindrical coil compression springs are located inside the guiding sleeves and symmetrical to their axes. The lower bearing surfaces of springs rest in round disks from antifriction material and the upper ones - in the cap covering the cast polyurethane layer with a gap. By means of a fastening element the cover is connected to a load bearing threaded element, for example, a bolt with its head being covered by the cast polyurethane layer. The sleeves on the side of the open part are fitted by ring flanged edges, coaxial sleeves' axes on which resilient rings are fixed with a gap in respect to the inner cap surface and serve as resilient limiters of moving elements of the vibration absorber. Resilient damping mesh elements are set under the disks of the guiding sleeves; they are made as pieces of off-grade rope of different diameter mixed up with the scraps of polyurethane products.EFFECT: increased efficiency of space vibration absorption and simplified design and installation.2 cl, 1 dwg |
